Forth, the Language.
Forth is a different language. It’s aged and a little weird.
What’s cool about it? It’s a very low-level and minimal language without any automatic memory management. At the same time, it easily scales to become a very high-level and domain-specific language, much like Lisp. Compared to C64 Basic, Forth is more attractive in almost every way.
It is a lot more fast, memory effective and powerful. Compared to C, specifically cc65, the story is a little different. It’s hard to make a fair comparison. Theoretically Forth code can be very memory efficient, and it’s possible to make Forth code that is leaner than C code. But it is also true that cc65 code is generally much faster than Forth code.

The year was 1978. Atari was at the top of the video gamming world with its 2600 VCS game console. Atari management looked around and saw a new and potentially lucrative market just beginning to take shape. This market was the Home Computer Market. They saw a market with relatively few major competitors and Atari was in a great position to market a computer of their own. They, after all, were a trusted household name, everyone owned an Atari or knew someone who did!
So December of 1978 Atari introduced the 400 and 800 series computers. The actual computers were not delivered until late 1979 due to production problems. The 400 was a scaled down version of the Atari 800. Introduced as an entry level computer based on the same MOSTEK 6502A processor running at 1.70 MHz with 16K of user RAM built in. It had a membrane style keyboard (not very touch type friendly) with 62 touch sensitive keys and 4 special keys to the right of the keyboard.
It stood out amongst the other computer offerings of the day with its graphics and sound capabilities. It was capable of producing 128 colors on the screen using the CTIA video processor and up to 256 colors with the upgraded GTIA video processor chip used on later versions of the computer. The 400 was first amongst the early computers to be able to display 4 programmable screen objects simultaneously called ‘Player-missiles’ (also known as ‘Sprites’ on Commodore computers). This was at a time when the most computers produced only monochrome displays or very primitive 8 color screens. The graphics were handled by a custom chip called the “ANTIC” (CTIA/GTIA). This chip was designed to work as a sort of co-processor to take the work load away from the main processor to display graphics and color on the screen.
The team that developed the custom chips inside the 400 and 800 was headed by Jay Miner who later, after leaving Atari, headed the teams who developed the custom chips that surrounded the Motorola MC68000 processor that powered arguably the most advanced computer of its time, The Amiga 1000!

This is a little description of the repair of a Radio Shack TRS-80 Model 1 for a Friend.
The computer comes with several problems.
Finding the cause of the fault has not been easy, i had to ask for a help to Ian, this dude is an expert of TRS-80 repairs.
How you can see from the photos, i had to replace a number of IC.
Stage of the defect (before and after):
Keyboard repair (replacement of internal contacts):

from Wikipedia:
TRS-80 was Tandy Corporation’s desktop microcomputer model line, sold through Tandy’s Radio Shack stores in the late 1970s and early 1980s, and one of the earliest mass-produced personal computers. The first units, ordered unseen, were delivered in November 1977, and rolled out to the stores the third week of December.
The line won popularity with hobbyists, home users, and small-businesses. Tandy Corporation’s leading position in what Byte Magazine called the “1977 Trinity” (Apple, Commodore and Tandy) had much to do with Tandy’s retailing the computer through more than 3,000 of its Radio Shack storefronts. Notable features of the original TRS-80 included its full-stroke QWERTY keyboard, small size, its floating point BASIC programming language, an included monitor, and a starting price of $600.
The pre-release price was $500 and a $50 deposit was required, with a money back guarantee at time of delivery. One major drawback of the original system was the massive RF interference it caused in surrounding electronics. Stricter FCC regulations on interference led to the Model I’s replacement by the Model III.
Radio Shack announced the TRS-80 (Tandy Radio Shack) at a New York City press conference on August 3, 1977. It cost $399, or $599 with a 12″ monitor and a Radio Shack tape recorder as datacassette storage. Before this, the most expensive product Radio Shack sold was a $500 stereo.
The company hoped that the new computer would help Radio Shack move into higher-priced products, and improve its “schlocky” image among customers. Small businesses were the primary target market, followed by education, then consumers and hobbyists. Despite its hobbyist customer base, Radio Shack saw hobbyists as “not the mainstream of the business”. Although the press conference did not receive much media attention due to a terrorist bombing elsewhere in the city that day, “six sacks of mail” arrived at company headquarters asking about the computer, and over 15,000 people called Tandy to purchase a TRS-80, paralyzing its switchboard.
Unlike competitor Commodore—which had announced its PET several months earlier but had not yet shipped any—Radio Shack began shipping computers by September. Still forecasting 3,000 sales a year, the company sold over 10,000 TRS-80s Model Is in its first one and a half months of sales, and over 200,000 during the product’s lifetime.

Turbo Chameleon 64 is an extremely user-friendly cartridge that can be used without opening the computer. It is just plugged to the expansion port of the C64.
The Turbo Chameleon 64 cartridge can also be operated as a stand-alone unit (since it’s basically an FPGA computer like the C-One or the Minimig in a C64 cartridge case), replacing the computer, the floppy drive and the heavy power supply.
When used as a stand-alone unit, a USB power adapter or active USB hub can be used as a power source.

SNDH archive v3.4 released. 73 SNDH-files added or updated!
Ever since the birth of the Atari ST, different chip music formats have had different ways to use them. If you are coding a chip music player for the Atari ST you would have to use dozens and dozens of special ways to replay music.
But in the mid 90′s, BDC of Aura crew became tired of this inelegant system and decided to fix the issue once and for all. He then created the ‘SNDH’ file format. SNDH is actually the original songfile and replaycode with a header bolted on top of the music and replayer. The header has a unified calling interface no matter what type of chip music is hidden beneath it, and it has extended datas about the music.

I have customized the keyboard of my C64 with my alias. I have used some keys of a broken C16.
